Training for Team Players
One of the most obvious things masters athletes notice as we age is that we get slower. While some aging athletes I know may be faster than when they were younger through training smarter or through using a more scientific approach to their training, in general the frustration of slowing down hits us all.
With few exceptions, my experience in masters sport is that too many aging athletes use antiquated team sport training methods or just play the game socially and expect to perform at a high level. According to the training principle of specificity, this is not possible. We need to analyse what the team player needs and train those qualities correctly.
